“…In relation to overall patient satisfaction after ICL implantation, 88% of high myopic patients were satisfied or very satisfied according to the questionnaire, which used a Quality of Life Impact of Refractive Correction [ 9 ]. However, patients who were dissatisfied with the surgery reported dissatisfaction with night vision.…”

Purpose To compare the visual and refractive outcomes and night vision performance questionnaire results between V4c and V5 implantable Collamer lenses in a prospective, randomized, multicenter study. Settings Four refractive surgery centers. Design Prospective randomized multicenter single-masked comparative study. Methods Twenty-three patients were enrolled in this study. A conventional V4c model (EVO Visian ICL) was implanted in one eye, and a V5 model (EVO+ Visian ICL), which has a larger optic diameter than the V4c model, was implanted in the contralateral eye. The uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) were evaluated before and 6 months after surgery. At 6 months after surgery, a questionnaire on night vision disturbances was administered. The efficacy, safety, and predictability of the two implanted ICL models were compared. Results There were no significant differences in the postoperative UDVA and CDVA between the two ICL models. The mean efficacy indexes for the V4c and V5 lenses were 1.16 ± 0.22 and 1.03 ± 0.23, respectively. The mean safety indexes of the V4c and V5 lenses were 1.21 ± 0.20 and 1.19 ± 0.20, respectively. The night vision performance questionnaire revealed that 7 patients (37%) noticed a difference in visual performance between the eyes, and all of them reported that they could see better at night with the V5-implanted eye compared with the V4c-implanted eye. Conclusion The V4c and V5 ICL models achieved similar visual and refractive outcomes, whereas the V5 model showed a possible advantage in reducing night vision disturbances.

“…Implantable Collamer Lens (ICL) is a posterior chamber phakic intraocular lens, and it has been proven to be safe, effective, predictable, and reversible for the correction of myopia and myopic astigmatism. [1][2][3] ICL implantation, as an essential component of refractive surgeries, has recently gained popularity among patients unsuitable for corneal refractive surgeries. 4,5 Since the ICL haptic footplates are placed in the ciliary sulcus, fully recognizing the anatomic structures of the ciliary sulcus, especially the ciliary sulcus-to-sulcus (STS) diameter, would be beneficial for calculating an ICL's proper size and power accurately, improving ICL rotational stability, and minimize the incidence of postoperative complications.…”

Purpose To assess the ocular anterior segment characteristics in myopic eyes intended for ICL surgery with horizontal ciliary sulcus-to-sulcus (STS) diameters being greater than vertical STS diameters. Methods This retrospective, comparative case study included 1230 eyes of patients who underwent ICL implantation for the treatment of myopia or myopic astigmatism at the Zhongshan Ophthalmic Center from September 2020 to November 2021. The myopic eyes were divided into two groups according to the relatively long diameter of the ciliary sulcus. General parameters and anterior chamber parameters were compared between the two groups. Results 1230 eyes of 694 patients were included. The proportion of myopic eyes with longer horizontal STS diameters was 4.63%. Horizontal STS distances exceeding vertical meridians in these eyes were mainly attributed to the shortening of vertical STS distances (horizontal STS: P = 0.112; vertical STS: P < 0.001). Eyes with longer horizontal meridians of the ciliary sulcus displayed larger steep keratometry value ( P = 0.001), larger corneal volume ( P = 0.002), larger corneal astigmatism ( P < 0.001), larger ocular residual astigmatism ( P = 0.017), worse visual acuity (logMAR UDVA: P = 0.021; logMAR CDVA: P = 0.001), and more iridociliary cysts ( P = 0.017) compared to eyes with vertically oval shapes. Conclusion Myopic eyes with longer horizontal STS diameters are commonly accompanied by a change in corneal morphology and more iridociliary cysts. The anatomical features of the ciliary sulcus should be given sufficient consideration to ICL size and placement selection, contributing to more personalized and precise surgery.
